For mountainous areas, however, measurements should be taken from an exposed clearing in the trees. If 0.4 inches falls on the ground, it gets reported as “traces.” Similarly, if 50 percent of the ground is covered with snow, it is reported as “traces” (T). To get an accurate measurement of snowfall depth, you need to know the amount of snow that has fallen on the ground. The snowdepth in Mount McLoughlin is about 50 inches higher than average for February 1 of this year. At the highest elevation, Chinook Pass recorded more than 200 inches of snow. The snowpack along the Cascades averages about 15 feet, with a few spots below normal. Other areas report snowpacks that are less than normal. The Cascade Mountains have reported snowpacks of 100 to 150% of normal. The graph below is a summary of average snowdepths for 10 of the state’s most important sites. The spreadsheet provides a comprehensive view of snow depth throughout the winter and early spring. The data includes measurements from Mount Baker to Mount Hood and are updated semimonthly.
